About
Acacia leiocalyx, commonly known as blackwattle, early black wattle, early flowering black wattle, lamb's tail wattle or curracabah is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is a shrub or tree with fissured, flaky bark, very narrowly elliptic to narrowly elliptic, more or less straight to sickle-shaped phyllodes, spikes of pale yellow, sometimes lemon-yellow flowers and linear, leathery pods slightly constricted between the seeds.
Where it grows
Subspecies herveyensis is restricted th south-east Queensland, where it is found from Yeppoon and south-east to Fraser Island and south to Gympie where it grow in sand beach scrub or in clay soils in forest. It occurs with subsp. leiocalyx in the Gympie-Maryborough area.
Uses
The timber is colourful but splits easily even with the end grain sealed.The seeds and gum are apparently edible, but caution should be taken - especially as there are so many difficult to identify similar species.
